ChatSlide vs deckhost

ChatSlide turns documents, topics, and research into presentations using AI generation and summarization. Users can upload notes or files, import material from supported sources, or enter a topic; the platform arranges content into slides with layouts, images, and speaker notes. Its 19 editing tools can add examples, rewrite content by grade level, and refine slides. Upload formats include PDF, DOCX, PPTX, TXT, and images; content sources also include URLs, YouTube, PubMed, OpenAlex, and ClinicalTrials.gov. Presentations can be exported as PowerPoint, PDF, or Keynote, and decks can be rendered as narrated videos with AI voiceover in more than 30 languages. The free tier includes 100 credits and PDF export; PowerPoint export is paid, and no credit card is required to start. Paid plans list project limits from 30 to 60 slides. Presentations are private by default, and free-plan uploads may be deleted after up to 30 days.

deckhost turns plain-text enhanced Markdown into presentations that can be published as shareable links. Users edit slide text directly and see a live preview; presentations support keyboard navigation, fullscreen mode, 12 reveal styles, math styling, syntax highlighting and background controls. AI use can rely on the user's Anthropic or OpenAI API key, and the product provides an MCP server for Claude Desktop and Claude Code. VS Code and Cursor extensions add live preview, speaker notes and one-click publishing. deckhost can import Marp frontmatter and map common directives to its own equivalents. Local work through the CLI, MCP server and presentation engine is free forever and needs no account; the CLI can also build static HTML for separate hosting. Published decks open in a browser without an account. The free plan is free, billed forever, with five published public decks and 100 API calls per day. Pro is $20 a month, and Team is $29 a month.
